1.) DNA replication is a process where the double helix is unwound and each strand is replicated to create another. This occurs in all replication of the body cells, or reproductive cells, a common process called mitosis.
2) The original DNA molecule is exactly the same as the replicated molecule, but the original is called the parent cell and the replicated molecule the daughter cell.
3) Enzymes act as catalysts/proofreaders of DNA replication. For example, Primase synthesizes RNA primer, or DNA ligase joins DNA strands together.
